FLUID-PUMP.

SPECIFICATION forming part of Letters Patent No. 439,'792, dated November 4, 1890.

Application filed January 16, 1890. Serial No. 337,079. (No model.)

To all whom it may concern:

Be it known that I, IMLE E. STOREY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fluid-Pumps, of which the following is a specification.

This invention relates to fiuid-pumps. It belongs to the class of multi-cylinder punps in which the pist-ons are driven by a single central crank-shaft.

The objects of the invention are to provide a pump of a variable Capacity which shall be cheap of Construction, occupy a small space, be efticient in operation, and well adapted for use in Inines.

The invention consists of the details of construction, which will now be described with reference to the acconpanying drawings, in

which- Figure 1 represents a side elevaton of the pump; Fig. 2, a horizontal section of same; Fig. 3, a vertical section taken on line w oc of Fig. 4; Fig. 4, a similar section taken on line y y of Fig. 3, and Fig. 5 a side elevation with parts in section of a Sinking pump and motor for use in Inines.

Beferring to the drawings by letter, A represents the frame of the pump. It consists of a single casting having two concentric walls a, and a', the for-mer of which is cylindrical and the latter made of cylindrical and plane portions. 'The space between these walls is inclosed by two plane heads a and a and the cylindrical space in the center is covered by two heads w* and a which are slightly concaved to bring the bearings which they contain inside as far as possible, thereby permitting of elongated bearings without occupying an unnecessary amount of space. In these bearings is mounted the shaft B of the pump, which extends out at one side, where it carries a gear-wheel B' which may be driven by an electric or other motor. Between its bearings the shaft has formed upon it two cranks, standing diametrically opposite each other. The shaft-bearings are supplied with oil from oil and waste boxes b b. The oil is carried along the journals and into the cylindrical chamber, where itis thrown about and thoroughly lubricates the parts.

In the main casting are formed four cylinders C C and C' C'. The cylinders C C are arranged nearly in the same plane, while the cylinders C' C'are in a different but parallel plane. The cylinders are spaced around the frame ninety degrees apart. The space between the walls a, a', & and 66 constitutes the water chambers and passages. On each side between the pair of cylinders vertical central diaphragms a (1 are formed or cast. These divide the sides of the pump each into two water spaces or Channels. Above and below the space between the cylinders is all open, the space below (represented by E) serves as a receiving and distributing chamber for the inflowing water, while the space above (represented byE') serves as a receiving-chanber for the outgoing water. An air-chamber E may be connected With chamber E' for the usual purpose.-

Referring to Fig. 3, the side channels for the water lead from chanber E to the right and to the left. The passage to the right is located this side of the diaphragn a and is terminated by the upper right-hand cylinder C. The passage to the left is located back of the diaphragm a and is terminated by the upper left-hand cylinder O'. Likewise there are passages leading to outlet-chamber E', the one on the right being back of diaphragm its inner limit being the lower left-hand cylinder O. Connected with each cylinder is a water-chamber c c, &c. These chambers extend across the pump and communicate with the chambers on each side of the diaphragtn through valves c' c' and 0 0 there being two valves for each cyllnder, one opening inward to adnit water to chambers c and the other opening outward to allow water to escape from said chambers.

In each of thecylinders is placed a removable lining d of brass or brass alloy. This is inserted in place through opening in the main casting covered by cap d', and is held in place by the nut (1 The pistons in the cylinders standing opposite each other are connected by piston-rods with the same crank. It is obvious that the brass cylinders and the pistons may be substituted by others of different diameter-s, thus varying the Capacity of the pump.

Water is drawn into the pump through passages F F, which lead to chamber F', thence IOO through inwardly-opening valves f to the distrbution-chamber E. Thenee the water divides, a part going to the right over cylinder C' and the remainder to the left under cylinder C. Then when the pistons are drawn ont of the cylinders or toward the center of the punp the water forces its Way through valves e' nto chambers c, and 'when the piston returns the p'essure upon the water thereby closes Valves 0' and opens valves c, which allows the water to escape into the passages communicating with receiving-chanber E', and thence through the outlet-passage Gr.

The compactness of this pump renders it particularly adaptable for use in mines either as a stationary pump or a Sinking punp. As a Sinking pump, I have shown it connected with an electric motor and in asuitable frane. The punp itself is represented by M. In this nstance it is turned on its side. The pipe M leads down into the mine and the outletppe s connected at V. The main shaft of the pump is stepped in a socket in the pipe M'. It extends through the pump and carres on its npper end the gear-wheel m, having internal teeth. To the npper side of the pump-fraine is bolted or otherwise Secured the frame O, which supports at considerable distance above the pump the electric motor P, the armature-shaft P' of which is placed in line with the punp-shaft. The lower end ture-shaft is forned in an extension of the frane O'. This extension is also provided with an eye o', with which ablock and taekle may be enga'ed for the purpose of raising and lowering the punp in the mining-shaft.

Having thus described my invention, I claim- 1. In a nulti-cylnder pump, a casing having an annular interior space apart of which constitutes a chamber on one side tor the incoming fiuid and another part a chanber on the opposite side for the outgoing fluid, the spaces on each side between the two chambers being dividedinto two channels by central diaphragms, one of the channels on each side communicating with the chamber for the incoming fluid and the other channel on each side communicating with the chanber for the outgoing fluid, and a cylinder on each side of the two daphragms and two valves for each cylinder, one located on each side of the diaphragns and altording communication between the cylinder and the respecti\ e channels on each side of the diaphragm, substantially as set fol-th.

2. The combination, with a pump and its central shaft, of an electric motor having its armature-shaft in line With the pump-shatt and geared to said shaft, and a frane connecting the pump and motor together, said frame having an extension whereby the punp .the armature-shaft P' has a hearing.

and motor nay be Suspended.

In witness whereof I have hcrennto signed my name in the presence of two subscribing witnesses.
